I have this CSS on some messages in a Ui I'm working on.
opacity: 0;
animation-name: fadeIn;
animation-duration: 1s;
animation-delay: 0.3s;
animation-fill-mode: forwards;
#keyframes fadeIn {
0% {
opacity: 0;
}
100% {
opacity: 1;
}
}
It fades in new items. Works great EXCEPT.... it fades ALL messages when the page loads. I ONLY want messages to fade in if they are NEW. Imagine a new message coming into an existing list.
Is there a way to tweak this animation to not trigger on page load? I could probably rig something with JS, but was curious if there is a pure CSS way to do this.
We gotta find a way to tell css which are new and which are old... we could use a property within the object perhaps?
js where we set the class based on the status field being 'new' or otherwise:
dataSet.map((item, key) => {
return (
<div className={item.status === "new" ? "newClass" : "oldClass"}>
{item.name} - {item.status}
</div>
);
})
sample stackblitz
Is there an equivalent for...
$.fx.off = true;
...in the world of pure css animations/transitions?
I'm working on a site that has tons of entry animations using both jquery and css, such that every time I change something and reload the page I'm stuck having to wait ten seconds for the entry anims to complete. It's pretty tedious.
This will make all animations and transitions hop to the last frame instantly once started, and also removes the delays:
* {
-webkit-animation-duration: 0s !important;
animation-duration: 0s !important;
-webkit-animation-delay: 0s !important;
animation-delay: 0s !important;
-webkit-transition-duration: 0s !important;
transition-duration: 0s !important;
-webkit-transition-delay: 0s !important;
transition-delay: 0s !important;
}
Demo
To apply it programmatically, change the selector to .no-anim * and apply the no-anim class to the <html> (or another containing element). Demo
I haven't tested this throughout yet, but it seems to work nicely for simple use cases at least. Feel free to adapt it to your needs, comment and improve.
There's no way of globally turning off CSS animations, however you could use a link to simulate animations being 'turned off':
Assuming your animations are bound normally:
body .elementClassName {
transition: propertyName 10s linear;
}
body:target .elementClassName {
transition: none;
transition: propertyName 0 linear;
}
This way, assuming that your body element has an id (for example <body id="bodyElementID">), if the page is loaded normally, at http://example.com/page.html transitions will occur, however if the page is loaded as: http://example.com/page.html#bodyElementID the transitions will not occur.
This is, without a demonstration of your real HTML a very generic overview of the possibility, but it's the only way I can think of.
There is no way to universally turn off CSS animations.
If you want to do something like this, place the animation pieces in a separate CSS class:
.AnimationOfWhatever {
-webkit-animation: entryAnimation 10s;
-moz-animation: entryAnimation 10s;
-o-animation: entryAnimation 10s;
-ms-animation: entryAnimation 10s;
animation: entryAnimation 10s;
}
and apply that class on your first load via jQuery (since you mentioned jQuery).
$('.ElementToAnimate').one('load',function(){
$(this).addClass('AnimationOfWhatever');
});
This will only load the animation once. If you want to only add that class once, create localStorage value and check that value:
$(function(){
if(localStorage['loaded'] === undefined){
localStorage['loaded'] = 'true';
}
$('.ElementToAnimate').on('load',function(){
if(!JSON.parse(localStorage['loaded'])){
$(this).addClass('AnimationOfWhatever');
}
});
});
This will only run the animation once across all pages.
Is it possible to use CSS3 transition animation on page load without using Javascript?
This is kind of what I want, but on page load:
image-slider.html
What I found so far
CSS3 transition-delay, a way to delay effects on elements. Only works on hover.
CSS3 Keyframe, works on load but are extremly slow. Not useful because of that.
CSS3 transition is fast enough but don't animate on page load.
You can run a CSS animation on page load without using any JavaScript; you just have to use CSS3 Keyframes.
Let's Look at an Example...
Here's a demonstration of a navigation menu sliding into place using CSS3 only:
#keyframes slideInFromLeft {
0% {
transform: translateX(-100%);
}
100% {
transform: translateX(0);
}
}
header {
/* This section calls the slideInFromLeft animation we defined above */
animation: 1s ease-out 0s 1 slideInFromLeft;
background: #333;
padding: 30px;
}
/* Added for aesthetics */ body {margin: 0;font-family: "Segoe UI", Arial, Helvetica, Sans Serif;} a {text-decoration: none; display: inline-block; margin-right: 10px; color:#fff;}
<header>
Home
About
Products
Contact
</header>
Break it down...
The important parts here are the keyframe animation which we call slideInFromLeft...
#keyframes slideInFromLeft {
0% {
transform: translateX(-100%);
}
100% {
transform: translateX(0);
}
}
...which basically says "at the start, the header will be off the left hand edge of the screen by its full width and at the end will be in place".
The second part is calling that slideInFromLeft animation:
animation: 1s ease-out 0s 1 slideInFromLeft;
Above is the shorthand version but here is the verbose version for clarity:
animation-duration: 1s; /* the duration of the animation */
animation-timing-function: ease-out; /* how the animation will behave */
animation-delay: 0s; /* how long to delay the animation from starting */
animation-iteration-count: 1; /* how many times the animation will play */
animation-name: slideInFromLeft; /* the name of the animation we defined above */
You can do all sorts of interesting things, like sliding in content, or drawing attention to areas.
Here's what W3C has to say.
Very little Javascript is necessary:
window.onload = function() {
document.body.className += " loaded";
}
Now the CSS:
.fadein {
opacity: 0;
-moz-transition: opacity 1.5s;
-webkit-transition: opacity 1.5s;
-o-transition: opacity 1.5s;
transition: opacity 1.5s;
}
body.loaded .fadein {
opacity: 1;
}
I know the question said "without Javascript", but I think it's worth pointing out that there is an easy solution involving one line of Javascript.
It could even be inline Javascript, something like that:
<body onload="document.body.className += ' loaded';" class="fadein">
That's all the JavaScript that's needed.
I think I have found a sort of work around for the OP question - instead of a transition beginning 'on.load' of the page - I found that using an animation for an opacity fade in had the same effect, (I was looking for the same thing as OP).
So I wanted to have the body text fade in from white(same as site background) to black text colour on page load - and I've only been coding since Monday so I was looking for an 'on.load' style thing code, but don't know JS yet - so here is my code that worked well for me.
#main p {
animation: fadein 2s;
}
#keyframes fadein {
from { opacity: 0}
to { opacity: 1}
}
And for whatever reason, this doesn't work for .class only #id's(at least not on mine)
Hope this helps - as I know this site helps me a lot!
CSS only with a delay of 3s
a few points to take here:
multiple animations in one call
we create a wait animation that just delays the actual one (the second one in our case).
Code:
header {
animation: 3s ease-out 0s 1 wait, 0.21s ease-out 3s 1 slideInFromBottom;
}
#keyframes wait {
from { transform: translateY(20px); }
to { transform: translateY(20px); }
}
#keyframes slideInFromBottom {
from { transform: translateY(20px); opacity: 0; }
to { transform: translateY(0); opacity: 1; }
}
Well, this is a tricky one.
The answer is "not really".
CSS isn't a functional layer. It doesn't have any awareness of what happens or when. It's used simply to add a presentational layer to different "flags" (classes, ids, states).
By default, CSS/DOM does not provide any kind of "on load" state for CSS to use. If you wanted/were able to use JavaScript, you'd allocate a class to body or something to activate some CSS.
That being said, you can create a hack for that. I'll give an example here, but it may or may not be applicable to your situation.
We're operating on the assumption that "close" is "good enough":
<html>
<head>
<!-- Reference your CSS here... -->
</head>
<body>
<!-- A whole bunch of HTML here... -->
<div class="onLoad">OMG, I've loaded !</div>
</body>
</html>
Here's an excerpt of our CSS stylesheet:
.onLoad
{
-webkit-animation:bounceIn 2s;
}
We're also on the assumption that modern browsers render progressively, so our last element will render last, and so this CSS will be activated last.
add this to your css for fade in animation
body{animation: 2s ease-out 0s 1 FadeIn;}
#keyframes FadeIn {
0% {
opacity:0;
}
100% {
opacity:1;
}
}
increase the ease-out time if you want it to load slower
Even simplier solution (still with [one line inline] javascript):
Use this as the body tag:
Note that body. or this. did not work for me. Only the long ; querySelector allow the use of classList.remove (Linux Chromium)
<body class="onload" onload="document.querySelector('body').classList.remove('onload')">
and add this line on top of your other css rules.
body.onload *{ transform: none !important; }
Take note that this can apply to opacity (as requested by OP [other posters] ) simply by using opacity as a transition trigger instead. (might even work on any other css ruling in the same fashion and you can use multiple class for explicity delay between triggering)
The logic is the same. Enforce no transform (with :none !importanton all child element of body.onloadand once the document is loaded remove the class to trigger all transition on all elements as specified in your css.
FIRST ANSWER BELOW (SEE EDIT ABOVE FOR SHORTER ANSWER)
Here is a reverse solution:
Make your html layout and set the css accordingly to your final result (with all the transformation you want).
Set the transition property to your liking
add a class (eg: waitload) to the elements you want to transform AFTER load. The CSS keyword !important is the key word here.
Once the document is loaded, use JS to remove the class from the elements to to start transformation (and remove the transition: none override).
Works with multiple transition on multiple elements. Did not try cross-browser compatibility.
div {
width: fit-content;
}
#rotated {
transform: rotate(-50deg)/* any other transformation */
;
transition: 6s;
}
#translated {
transform: translate(90px)/* any other transformation */
;
transition: 6s;
}
.waitload {
transform: none !important;
}
<div id='rotated' class='waitload'>
rotate after load
</div>
<div id='translated' class='waitload'>
trasnlate after load
</div>
<script type="text/javascript">
document.addEventListener('DOMContentLoaded', init);
function init() {
[...document.querySelectorAll('.waitload')]
.map(e => e.classList.remove('waitload'));
}
</script>
Similar to #Rolf's solution, but skip reference to external functions or playing with class. If opacity is to remain fixed to 1 once loaded, simply use inline script to directly change opacity via style. For example
<body class="fadein" onload="this.style.opacity=1">
where CSS sytle "fadein" is defined per #Rolf,defining transition and setting opacity to initial state (i.e. 0)
the only catch is that this does not work with SPAN or DIV elements, since they do not have working onload event
start it with hover of body than It will start when the mouse first moves on the screen, which is mostly within a second after arrival, the problem here is that it will reverse when out of the screen.
html:hover #animateelementid, body:hover #animateelementid {rotate ....}
thats the best thing I can think of: http://jsfiddle.net/faVLX/
fullscreen: http://jsfiddle.net/faVLX/embedded/result/
Edit see comments below:
This will not work on any touchscreen device because there is no hover, so the user won't see the content unless they tap it. – Rich Bradshaw
Ok I have managed to achieve an animation when the page loads using only css transitions (sort of!):
I have created 2 css style sheets:
the first is how I want the html styled before the animation...
and the second is how I want the page to look after the animation has been carried out.
I don't fully understand how I have accomplished this but it only works when the two css files (both in the head of my document) are separated by some javascript as follows.
I have tested this with Firefox, safari and opera. Sometimes the animation works, sometimes it skips straight to the second css file and sometimes the page appears to be loading but nothing is displayed (perhaps it is just me?)
<link media="screen,projection" type="text/css" href="first-css-file.css" rel="stylesheet" />
<script language="javascript" type="text/javascript" src="../js/jQuery JavaScript Library v1.3.2.js"></script>
<script type='text/javascript'>
$(document).ready(function(){
// iOS Hover Event Class Fix
if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)) ||
(navigator.userAgent.match(/iPad/i))) {
$(".container .menu-text").click(function(){ // Update class to point at the head of the list
});
}
});
</script>
<link media="screen,projection" type="text/css" href="second-css-file.css" rel="stylesheet" />
Here is a link to my work-in-progress website: http://www.hankins-design.co.uk/beta2/test/index.html
Maybe I'm wrong but I thought browsers that do not support css transitions should not have any issues as they should skip straight to the second css file without delay or duration.
I am interested to know views on how search engine friendly this method is. With my black hat on I suppose I could fill a page with keywords and apply a 9999s delay on its opacity.
I would be interested to know how search engines deal with the transition-delay attribute and whether, using the method above, they would even see the links and information on the page.
More importantly I would really like to know why this is not consistent each time the page loads and how I can rectify this!
I hope this can generate some views and opinions if nothing else!
If anyone else had problems doing two transitions at once, here's what I did. I needed text to come from top to bottom on page load.
HTML
<body class="existing-class-name" onload="document.body.classList.add('loaded')">
HTML
<div class="image-wrapper">
<img src="db-image.jpg" alt="db-image-name">
<span class="text-over-image">DB text</span>
</div>
CSS
.text-over-image {
position: absolute;
background-color: rgba(110, 186, 115, 0.8);
color: #eee;
left: 0;
width: 100%;
padding: 10px;
opacity: 0;
bottom: 100%;
-webkit-transition: opacity 2s, bottom 2s;
-moz-transition: opacity 2s, bottom 2s;
-o-transition: opacity 2s, bottom 2s;
transition: opacity 2s, bottom 2s;
}
body.loaded .text-over-image {
bottom: 0;
opacity: 1;
}
Don't know why I kept trying to use 2 transition declarations in 1 selector and (not really) thinking it would use both.
You could use custom css classes (className) instead of the css tag too.
No need for an external package.
import React, { useState, useEffect } from 'react';
import { css } from '#emotion/css'
const Hello = (props) => {
const [loaded, setLoaded] = useState(false);
useEffect(() => {
// For load
setTimeout(function () {
setLoaded(true);
}, 50); // Browser needs some time to change to unload state/style
// For unload
return () => {
setLoaded(false);
};
}, [props.someTrigger]); // Set your trigger
return (
<div
css={[
css`
opacity: 0;
transition: opacity 0s;
`,
loaded &&
css`
transition: opacity 2s;
opacity: 1;
`,
]}
>
hello
</div>
);
};
Not really, as CSS is applied as soon as possible, but the elements might not be drawn yet. You could guess a delay of 1 or 2 seconds, but this won't look right for most people, depending on the speed of their internet.
In addition, if you want to fade something in for instance, it would require CSS that hides the content to be delivered. If the user doesn't have CSS3 transitions then they would never see it.
I'd recommend using jQuery (for ease of use + you may wish to add animation for other UAs) and some JS like this:
$(document).ready(function() {
$('#id_to_fade_in')
.css({"opacity":0}) // Set to 0 as soon as possible – may result in flicker, but it's not hidden for users with no JS (Googlebot for instance!)
.delay(200) // Wait for a bit so the user notices it fade in
.css({"opacity":1}); // Fade it back in. Swap css for animate in legacy browsers if required.
});
Along with the transitions added in the CSS. This has the advantage of easily allowing the use of animate instead of the second CSS in legacy browsers if required.

Maintaining the final state at end of a CSS animation
(5 answers)
Closed 7 years ago.
Given the following CSS3 animation....
<style type="text/css" media="screen">
.drop_box {
-webkit-animation-name: drop;
-webkit-animation-duration: 2s;
-webkit-animation-iteration-count: 1;
}
#-webkit-keyframes drop {
from {
-webkit-transform: translateY(0px);
}
to {
-webkit-transform: translateY(100px);
}
}
</style>
<div class="drop_box">
Hello world
</div>
The Hello World text animates as expected dropping down 100px. However, at the end of the animation it jumps back to its original position.
Clearly this makes sense in CSSland. The animation has been applied and is no longer acting on the element so the original styles take effect. It seems slightly odd to me though - surely if one is animating an element into place then one would expect that placing to persist?
Is there any way of making the end position 'sticky' without having to resort to Javascript to tag a classname or style onto the element at the end of the animation to fix its altered properties? I know that transitions persist, but for the animation I have in question (the example is for demonstration purposes only) transitions don't give the level of control needed. Without this, it seems that complex animations are only of use for circular processes where the element ends up back in its original state.
You can use -webkit-animation-fill-mode to persist the end state (or even extend the start state backwards). It was added to WebKit a while ago, and shipped in iOS 4 and Safari 5.
-webkit-animation-fill-mode: forwards;
If you define the end state in the class then it should do what you want in the example:
.drop_box {
-webkit-transform: translateY(100px);
-webkit-animation-name: drop;
-webkit-animation-duration: 2s;
-webkit-animation-iteration-count: 1;
}
But if your animation is event driven anyway you will probably end up having to use a bit of JavaScript. The easiest way is to make the adding of the class with the end state in it be what triggers the animation to start.
--edit
See dino's answer for information on the animation-fill-mode property added in the April 2012 WD.
Just to add to the great answers here, you could use a javascript framework such as jQuery Transit that handles the CSS3 transitions for you.
Depending on how many transitions/effects you will be doing, this may be a better solution in keeping your code clean rather than keeping up with a large CSS file that has all of your effects in it.
This is a very simple one-liner that accomplishes what you want:
Javascript:
$(".drop_box").transition({y: "+=100px"}, 2000);
JS Fiddle Demo
I think what you might be looking for is:
0% {
-webkit-transform: translateY(0px);
}
100% {
-webkit-transform: translateY(100px);
}
This should leave it in the right place.
Yet another way to do this, just for kicks,
<style type="text/css" media="screen">

-webkit-animation-name: drop;
-webkit-animation-duration: 2s;
